FAQs
How does a home solar power system work and what equipment is installed?
A residential photovoltaic (PV) system converts sunlight into electricity using roof-mounted or ground-mounted solar modules. The DC power they create is routed to an inverter (or a set of micro-inverters) that changes it into the 240-V AC electricity your home uses. A bidirectional meter records the energy you export or import, enabling net-metering with Fort Loudoun Electric Cooperative or TVA’s Green Connect program. Optional equipment includes a battery bank for backup power and a monitoring gateway so you can track production from your phone or computer.
What does it cost to install solar in Friendsville and are there incentives?
Turn-key pricing for a typical 7–10 kW roof-mounted system in Blount County currently ranges from $2.40 to $3.00 per watt, or roughly $17,000–$28,000 before incentives. Homeowners can claim the 30 % Federal Solar Investment Tax Credit (ITC) through 2032, cutting that figure by nearly one-third. Tennessee exempts solar equipment from state sales tax and property-tax assessment, and TVA offers one-time performance-based incentives for systems that enroll in its Green Connect program. Low-interest green-energy loans are also available through local credit unions.
How long does the solar installation process take?
From the day you sign a contract, most residential projects reach energization in 6–10 weeks. Site evaluation and system design take 1–2 weeks, utility interconnection and permit approvals another 2–4 weeks, and physical installation usually only 1–3 days. After the final inspection, TVA swaps in a bidirectional meter and issues a Permission-to-Operate (PTO) notice, at which point the system goes live.
Will my solar panels still produce electricity on cloudy days or during East Tennessee winters?
Yes. Modern monocrystalline panels generate 10–40 % of their rated power under overcast skies and actually operate more efficiently in cooler temperatures. Friendsville receives about 4.3 sun-hours per day on an annual average, with production highest from March to October and lowest in December–February. Your installer sizes the array using National Renewable Energy Laboratory (NREL) data to ensure yearly output meets your energy goals despite seasonal variations.
How much upkeep do solar panels need and how long will they last?
Solar panels have no moving parts and require minimal maintenance—usually just a hose rinse if pollen or dust builds up, or an annual visual check for debris and shading. Inverters may need a firmware update every few years, and their power electronics typically carry a 10–25-year warranty. The panels themselves are warranted to produce at least 80–85 % of their original output after 25 years, but real-world data show many arrays still exceed 90 % after three decades.
If the utility grid goes down, will my solar system keep my house powered?
Standard grid-tied systems shut off automatically during an outage for line-worker safety. To keep critical loads running, you can add a battery storage system or a hybrid inverter with an emergency power outlet. Popular options in Friendsville include Tesla Powerwall, Enphase IQ Battery, and FranklinWH. These units island your home from the grid and power essentials like lights, refrigerators, and internet until the grid is restored or the sun comes back up to recharge the batteries.
